Enter Entropic Dynamics (ED), which is a reconstruction of quantum theory in which the principles of inference and information processing are held as sacrosanct. In ED, probabilities are Bayesian [1]}[2]}, they are manipulated using the rules of probability theory [3]}[4]}, and they are updated by the Maximum Entropy (ME) method [5]}-[6]}. End of story. The notion of `quantum probabilities' [7]}[8]} or `generalized probabilities' [9]}[10]} does not enter. Indeed, it makes no sense in ED to derive the `Born rule' from the notion of an `amplitude' \(\Psi \)  (see e.g., [11]}[12]}) — our goal is, rather, to derive the notion of an amplitude from the more fundamental concept of probability.
